About call routing
There are two major steps in Wave call processing: digit collection and call routing. It is
important to note that digit collection and call routing are two completely separate processes. In
the digit collection process, the PBX collects the digits sent from the call source until it has
enough digits to route the call. Once digit collection is complete, the PBX attempts to route the
call.
All calls that go through Wave pass through the First Digit Table. The first step in all Wave
routing decisions is made based on the first digit of the number dialed. The first digit determines
whether the call is routed to an internal or external destination.
When the destination is a user extension, the call is routed according to the user's active routing
list.
